I'm M Boopathi — a Full Stack Developer and IoT engineer. This is where I write down what I learn while building: ESP32 and embedded systems, Python backends, web development, Linux, AI and the technical SEO that makes any of it findable.
Your ESP32 is plugged in, the power LED is on, and Arduino IDE shows nothing under Tools → Port. Here are the seven causes I hit most often — charge-only cables, missing CP210x/CH340 drivers, held boot buttons — and exactly how to fix each one.
